This robot, called the Rydis H1004 II, roves around its owner’s home and filters the air as it goes. It is also designed to act as a safety system for elderly people living alone. It connects with a wrist band that can detect a fall, and can call for help if one occurs. The robot is made by South Korean company Moneual. It should arrive in the U.S. later this year, and will cost around $1,000.
